I recently had my built-in speakers stop working less than a year after purchasing my MacBook Pro 15".  About 24hrs ago, my built-in speakers were working fine.  At some point, I was using my bose headphones, and after I unplugged them, my speakers did not work.  I've confirmed that the sound is not muted.  I have sound visible on the desktop bar, but it is grayed out.  I looked on my system preferences for audio output, and my speakers are not listed as an option.  Only optical digital-out is an option besides my Apple TV. 

MacBook Pro (15-inch, Mid 2012), OS X Mountain Lion (10.8.2)
